BRITISH COMPANY COKE DISGHARGER FOR RETORTS'FOR THE GARBONIZATION OFGOAL AND THE DIKE Application filed March 14, 1932, Serial No. 598,852,and in Great Britain May 7, 1931.

This invention relates to coke discharging means for vertical retortsfor the carbonlzation of coal and the like, and has for its object toprovide improved and simpllfied d1scharging means of the intermittentlyoperating type. j v

The invention comprises a pivotally mounted coke chamber forming aclosed receptacle for'the coke with a hinged coke discharge door andlocking means therefor at one side thereof, and an arcuate projectionfor closing the connection between the coke chamber and the retort atthe opposite side thereof, and means for raising and lowering the cokechamber to make a gas tight joint between the arcuate projection and thebottom of the retort and for removing any pressure between said parts tofacilitate their relative movements.

The invention further comprises the arrangement in which the cokechamber is carried by eccentrics upon a shaft beneath it about which thechamber pivots, the shaft being turned to raise and to lower the cokechamber. j

The invention further comprises the arrangement in which the cokechamber has a fixed bottom sloping downwards towards the side of thechamber at which the discharge door is situated, the said door extendingto the level of the bottom of the chamber and when released by its catchopening automatically to permit of coke discharge.

The invention further comprises the arrangement in which the cokedischarge door is hinged o-r pivoted at its upper end and constitutespractically the whole of one side of the coke chamber.

The invention further comprises securing means for the coke dischargedoor which proj set through the bottom of the coke chamber and areoperated by a handle upon a cross shaft beneath the coke chamber, and aspring holding the securing means normally in service. 7

The invention further comprises the provision of a table movable up anddown within the coke chamber in order to control the rate of descent ofcoke into such chamber from the retort.v

Referring to the accompanying explanatory drawings Figure 1 is anelevation partly in section, illustrating the lower portion of a retortwith coke discharging means thereon ar,

we employ a pivotally'mounted coke cham-:

her a, which is adapted when coke discharge is to be effected to bebroughtto the position shown in Figure 3, beneath the steamingchamber 1) which is an extension ofthe retort proper 0, so that the cokecan drop into the coke chamber which is then swung to the pos tion shownin Figure 1 with an arcuate pro ection 03 at its upper end closing offthe lower end of the steaming. chamber 6 of the retort, and a door 6 atthe side of the coke chamber being opened to permit the discharge of thechamber contents.

The coke chamber is pivoted at its lower end, the pivot shaft f havingeccentric bushes g secured thereon which turn in upon the underside ofthe coke chamber, so as to apply sealing pressure between thearcuateprojection 03 on the coke chamber and the bottom of the steaming chamber6 to make a gas tight joint between the said parts.

The pivotal shaft f has a pair of slotted crank arms 2' thereon in whichengage the ends of a cross head 9' upon a screwed shaft is having a handwheel mthereon. It will be seen, therefore, that by turning thehandwheel m in one or other direction, the pivotal shaft can be turnedto cause the eccentrics 9 either (1) to raise the coke chamber a andcause the part d to make a gas tight joint with the bottom of thesteaming chamber 7),

parts It delivery ough the door.

or (2) to lower the coke chamber to allow it to be turned freely fromthe Figure 1 to the Figure 3 position, and vice versa.

It will be understood that the coke chain- 5 ber is only brought intoline with the retort and steaming chamber, as shown in Figure 3, whencoke discharge is to be eifected and then only for theishort periodnecessary for coke tofall into the chamber.

The delivery door 6 upon the coke chamber extends the full width andpractically the full depth ofthe latter. It is hinged at e at itsupperend and when the coke cham;

ber is in the delivery position; the release 'of the door catch a n willresult, in the door opening and moving to a Vertical position, as showninFigure 1.
